PURPOSE:To provide a calendered form low in thickness variation and excellent in glass, comprising an olefin polymer and an alpha-olefin-polyene copolymer-contg. polymer from an alpha-olefin-polyene copolymer and an olefin polymer. CONSTITUTION:The objective calendered form having the above-mentioned advantages can be obtained by calendering a resin composition produced by incorporating (A) 0.005-99wt.% of an alpha-olefin-polyene copolymer-contg. polymer prepared by (co)polymerization of an olefin to form an olefin polymer using a preliminary polymerization catalyst with (B) 99.995-1wt.% of an olefin polymer such as polypropylene or polyethylene. The preliminary polymerization catalyst which contains an alpha-olefin-polyene copolymer can be prepared by copolymerization between (1) a transition metal compound catalytic component and organometallic compound catalytic component (the metal in the latter component is group I, II, or III metal) and (2) a total of 0.01-2000g, per g of the former catalytic component, of an alpha-olefin and polyene compound. |
